Application filed. September 29, 1923. 'Serial No. 665,708. 7

" To all whom it co ncemf. I i i Be it, known that we, MAURICE .BRYAN.Looa'nsand EDWARD Bunnows LooMrs, subjects of the "King ofEnglandpresiding at Sherbrooke, in the'Provin'ce of: Quebec and Dominionof Canada, have invented certain .new and useful'Improvem'ents in Brickldin 'Machines, of which the following i a specificatio I I machineryand more-particularly toa novel and improved "mechanism'fon ejecting themoulded bricks: from bottomless mouldsas the same are successivelydelivered at thei iendflof the soft .mud brick machine, now

well knownin theart Oneofth'eobjects of our. inventionis to provide anovel and improved mechanism adapted .to beutilized inconnectiOnwith 9any soft ,mud brick machinewherein pal-. lets may be positioned beneath,the delivery tib1810fth8 bottomless moulds as they are [pushedforwardly, including provision for intermittently, jarring the saidmoulds so.

positioned beneath the; delivery table'to receive the green bricks.after. thesame are fjarred or loosened from,themould. includingprovision for. intermittently lifting. said moulds and conveying thesameto one side of v the, mechanism whereby the said bottom-'1 less mouldsmay be again introduced to the 40 delivery table ofthe soft mud machine.I

., To enable others sldlledin the art to fully comprehend the underlyingfeatures of. our invention that they may embody the same in the. variousmodifications in struck ture; and relationof parts contemplated,drawings depicting. a. preferred form have if A i been annexed'as a partof this disclosureand, in such} drawings, similarreferenc'e,charactersdenote correspondingpartsthrougb outjtheseverall'views, of which-.

Figure 3 is a plan.

; Figure 4 is an end view partly in section showing the lifting platesand cams in their relation to the bottomless moulds and pal lets.

like reference characters designate corresponding parts throughout theseveral views, 5 designates generally a power driven, soft-mudbrickmachine and 6' amold, constructed'v without a top or bottom, c011-7; tammg'o'neor more sections, the size of a brick of any'desired shape,and which we have designated as. a bottomless mold to be 'fed andreceive the clay or material Where- 'bythe brick is; shaped. A mouldpush or mould carrier is adapted to bereciprocated to engage theend-moulds so as to thrust the same forwardly on the delivery tablewhereby the next mould maybe inserted.

' .Positioned and-secured on the top of the mould, delivery table 7* ofthe soft mud machine isa heavy mould plate, having guards and guides ofangle lron secured or bolted on top of said plate soas to support andguide the bottomless molds and their contentsv during their travel fromthe time the empty molds arefed into thesoft mud machine until theyleave the end of the mold plate and are deposited on the pallet inztheproper position preliminary to being engaged by thelifting devicesubsequently to be referred to. The above. operation: is effected b'ythereciprocating mold push or mold gage clearly shown by Figs.

1 audit of the drawing.

Secured to the endof the soft mud ma- [chine dumping table, we haveprovided a Referring nowto the drawings, wherein w pallet delivery table9 adjusted by set screws at a point below the bottom of the molddelivery plate to accommodate and receive any form of pallet now incommon practice. Attached to the operating mechanism of the soft mudmachine or the mold push and gage, are two palletpush bars 11, one oneach side, which are under the mold plate, and slidable in brackets orguides 13, which push and urge the pallets forwardly as they are fedinto the side of the device in their proper position at the end of themold plate and beneath the bottomless, filled molds. which aresubsequently 3 disengaged from the green bricks. The sup- POltlHgstructure 8 is provided with guide plates 15 and a pair of liftingplates 16, the upper end of said lifting plates being. bent inwardly asindicated at 17 so as to engage the ends of the bottomless mold G as thesame is fed forwardly on the pallet,

The lifting plates 16 have attached thereto,

L-shaped bars 18, preferably riveted or i moulded to said lifting platesand movable The supporting structure 8 has therewith. mounted insuitable bearings 20, an operating shaft 21, driven by a sprocket andchain mechanism from the soft mud brick machine. A pair of cams 22, 2'3operable with the shaft 21 are adapted to engage the L-shaped bars 18 soas to actuate the lifting plates whereby the bottomless molds 6 may beraised into engagement with the spring 24:, secured to the supportingstructure. The cams 22, 23, keyed on the shaft 21 are provided withteeth 25 which are adapted to engage a lug 26 on each of the liftingplates so that when the cams rise over the lugs, a shaking or jarringaction will be imparted to the lifting plates and consequently to themolds 6 whereby the green bricks are loosened and deposited on thepallets 10. Since this action is intermittent due to the reciprocationof the pusher bar andthe actionof the cams, the pallets will be fed intimed relation so that the bottomless. moulds will be engaged by thelifting plates to freethe greenbricks therefrom whereupon the pallet andthe bricks may be removed from the end of the table 9 to the conveyor. e

. It will be observed that the shaft 21 is provided with a bevelled gear27 which is in mesh with a bevelled gear 28 on the shaft 29, mounted insuitable bearings on the supporting structure and horizontally extendingbars 30, as shown by Fig. 3 of the drawings. The shaft 29 also carries asprocket and chain drive 32, 33, which sprocket is trained over asprocket 34 on a second shaft Shaft 35 drives the shaft 36 throughsuitable sprocket andch'ain gear ing as further disclosed by'Figure-s 2and 4:. An idler sprocket 37 mounted on a shaft 38 cooperates with thesprocket on the shaft 86 and supports the delivery sprocket 35). Thesprocket 39 is provided with L-shaped wiper plates or bars 40 which areadapted to engage the ends of the bottomless molds as the same arepushed upwardly by the next succeeding mold and carries the sametransversely and over on the sides of the supporting structure. Themolds 6 being freed from the bricks, are then removed and again fedint-othe soft mud brick machine as above described.

It will be understood by those skilled in the art, that the operation ofthe cams are timed so that the lifting plates will engage thebottomlessmolds only asthe pallets are moved forward into position and after themolded bricks have been jarred loose and the smooth surface of the camsraise the lifting plates, the bottomless molds will be elevated and heldin position by the springs 24: until the next mold engages the same.This is clearly shown in Fig. 4 wherein the green bricks have beendeposited on the pallet and the mold raised, ready to be engaged by theconveyor. A filled mold, directly behind the green bricks is advanced bythe pushing mechanism as the operation continues. The L-shaped wiperplates or bars 40 of course engage the ends offthe bottomless molds asthey are elevated, transferring them horizontally of the machine asshown by Figs. 3 and 4.

Vhile we have illustrated and described our invention with some degreeof particularity, we realize that in practice various alterationstherein may be made. We therefore reserve the right and privilege ofchanging the formof the details of construction or otherwise alteringthe arrangement of the correlated parts without departing from thespirit of the invention or the scope of the appended claims.

Having thus described ourinvention, what we claim as new and desire tosecure by Unit-ed States Letters Patent is 1. In combination with thedelivery table of a soft mud brick making machine and bottomless mouldstherefor, a supporting structure adjacent the end of said table, palletsfor receiving the filled moulds from the delivery table, adriven shaft,cams keyed on the shaft, teeth on each of the cams, lifting plates forengaging the moulds, lugs on said lifting plates cooperating with theteeth of the cams to jar the bricks free from the moulds, andmeans forretaining ,the elevated moulds above the pallets.

2. In combination with the delivery table of asoft mud brick makingmachine and bottomless moulds therefor, a supporting structure adjacentthe end of said table, pallets for receiving the filled moulds from thedelivery table, reciprocating'rods operable by the machine for advancingthe pallets, a driven shaft, cams mounted on theshaft and operabletherewith, teeth on the surface of the cams, lifting Iates having lugsthereon engageablebythe teeth ofthe earns to jar the bricks loose fromthe moulds, resil- 1 ient' elements for engaging the ends of the mouldswhen elevated by the cams above the pallets, and a conveying mechanismfor transferring the free moulds.

testimony whereof we affix our signatures in presence of two witnesses.
